Introduction: Obstructive sleep apnea (OSA) is common among commercial drivers and associated with health/safety risks, leading several trucking firms to mandate OSA screening.

Methods: A total of 19,371 commercial drivers were screened for OSA with an online questionnaire (Somni-Sage[reg]) through employer mandates. Questionnaire and polysomnography results were analyzed retrospectively.

Results: Screening categorized 5908 drivers (30%) as higher risk. To date, employers have sent 2103 higher-risk drivers for polysomnography, demonstrating that 68% of high-risk drivers tested had an apnea–hypopnea index (AHI) greater than 10 and 80% had an AHI of 5 or more. A conservative prevalence estimate for OSA (AHI > 10) was 21% among the drivers studied.

Conclusions: Online screening followed by polysomnography for high-risk drivers demonstrates as many as 21% of commercial drivers may have OSA. Mandatory screening can have a high yield among commercial drivers.
